DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a concept diagram illustrating a lens processing management system (a lens design data use management system) 220 according to an embodiment.

In the embodiment, as shown in FIG. 1, a lens processing management system (a lens manufacturing system, and a lens design data use management system) 220 includes a lens processing device b1 including a lens processing section b17 that processes a lens based on design data, an authentication section (a restriction unit, and an authentication unit) 224 substantially attached to a lens material or a semi-finished lens product 222, and an authentication processing section 226 that performs an authentication process for processing of the lens using the authentication section 224.

In the embodiment, the semi-finished lens product 222 is provided from a lens designing enterprise C to a lens manufacturer B. In the embodiment, the authentication section 224 includes information (for example, authentication codes, and authentication parameters) used in authentication of use permission of design data, and is embedded in the semi-finished lens product 222. As an example, the authentication section 224 includes one authentication code corresponding to one semi-finished lens product 222. As another example, the authentication section 224 includes one or a plurality of authentication codes corresponding to a plurality of semi-finished lens products 222.

As an aspect of the authentication section 224, various authentication marks such as special marking and IC tag may be applied. The authentication section 224 embedded in the semi-finished lens product 222 is easily visible and/or detectable, or is not easily visible, and is detectable only through a predetermined device.

Alternatively or additionally, the authentication section 224 is attached to the semi-finished lens product 222, and is integrally shipped and transported. For example, the authentication section 224 may be provided in an object different from the semi-finished lens product 222. The authentication section 224 provided in the different object is easily visible and/or detectable, or is not easily visible, and is detectable only through a predetermined device.

An authentication section 22 may be minimally configured so as not to be easily visible, or may be configured to be substantially transparent. The lens manufacturer B pays the lens designing enterprise C at least for the semi-finished lens product 222 including payment for the authentication information of the authentication section 224.

In the embodiment, the design data is stored in a lens design data storing section b13, and the use thereof is restricted based on authentication. That is, as long as the use permission is not authenticated, the processing device b1 cannot use the design data. The authentication information (the authentication code, and the authentication parameter) of the authentication section 224 is input through an input unit (not shown), or is detected through a detection unit (not shown), and is analyzed by an analysis unit (not shown) as necessary.

The authentication processing section 226 performs an authentication process on the authentication information. The authentication process may include at least one of approval of provided information, confirmation of correspondence between provided information and registered information, verification of qualification or disqualification, configuration of identification information according to individual enterprises or individual devices, and confirmation of warranty or accuracy of procedure course. For example, in the authentication section 226, the design data can be read as long as a correct authentication code is not input. In the embodiment, when the authentication information is authenticated, the use restriction of the design data is released. In an example, the authentication processing section 226 may be configured as an example of the computer program. In another example, the authentication processing section 226 may include the detection unit, an analysis unit, and a computer program as necessary.

In an example, the authentication process may be performed in the lens processing device b1 using an authentication program provided together with or provided separately from design data. In this case, the authentication program is simple. In another example, the authentication process may be performed by the lens designing enterprise through the Internet. In this case, it is possible to avoid wrongful modification of the authentication processing process.

The authentication process may be performed based on one parameter or based on combination of two or more parameters. In an example of the authentication process using the plurality of parameters, the authentication program requires authentication information of the authentication section 224 and the identification information of the design data. In another example, the authentication program requires the authentication information of the authentication section 224, and the ID information of the lens processing device b1 (or the lens manufacturer). The identification information of the design data or the ID information of the lens processing device b1 (or the lens manufacturer) may be stored in the lens processing device b1 or may be stored in another object or medium. Additionally or alternatively, the authentication process may use an authentication support physical device (a security token).

In the embodiment, in the lens processing of the processing device b1, an authentication procedure using the authentication section 224 is required, and thus the processing of the lens wrongfully using the design data is restricted. The processing of the lens using a material or a semi-finished product different from the semi-finished lens product provided from lens designing enterprise C is restricted.

FIG. 2 is a concept diagram illustrating an example of another embodiment to which the lens processing management system (the lens manufacturing system, and the lens design data use management system) 220 shown in FIG. 1 is applicable. In FIG. 2, the lens designing enterprise C, the lens manufacturer B, and the lens store A are connected through the internet dl.

In FIG. 2, a server a2 managed by the lens store A such as a glasses store, a server b2 managed by the lens manufacturer B that processes a lens and delivers the lens to the store, and a server c2 managed by the lens designing enterprises C that designs the lens are connected to the internet dl. The lens processing device b1 connected to the server b2 can communicate a prescription data transmitting device a1 connected to the server a2, and a lens designing device (a data supply device) c1 connected to the server c2.

In the embodiment, the lens processing device b1 receives order data for placing an order of lenses and prescription data including information about lens prescription of a customer using a lens and a frame shape of glasses, from the prescription data transmitting device a1, and transmits the received prescription data to the lens designing device c1. The lens processing device b1 receives and stores the design data (hereinafter, referred to as lens design data) of the lens about the transmitted prescription data from the lens designing device c1.

As described above, the lens manufacturer B requests the lens designing enterprise C to design a lens, and pays a design fee for the provided lens. The design fee paid to the lens designing enterprise C by the lens manufacturer B is a design fee for processing per lens. For example, the lens manufacturer B has to pay the lens designing enterprise C for a design fee corresponding to the processing of each lens even in the processing of the lens using the same lens design data.

In the embodiment, the lens processing device b1 transmits the authentication code of the authentication section 224 attached to the semi-finished lens product 222 to the lens designing device c1 before performing the processing of the lens. In the lens designing device c1, the authentication processing section 226 performs the authentication process on the received authentication code, and transmits the authentication response that is the authentication result to the lens processing device b1. When the authentication response received from the lens designing device c1 is the authentication permission response, the lens processing device b1 can process the lens. The lens manufacturer B delivers the processed lens to the lens store A.

As described above, the lens design data use management system 220 determines the authentication code received from the lens processing device b1 by the lens designing device c1, and thus it is possible to appropriately manage the use state of the lens design data.

<Lens Processing Device>

Hereinafter, the lens processing device b1 and the lens designing device c1 shown in FIG. 2 will be described in detail.

FIG. 3 is a schematic block diagram illustrating a configuration of the lens processing device b1 according to the embodiment.

The lens processing device b1 includes a communication section b10, a prescription data transmitting and receiving section b11, a lens design data receiving section b12, a lens design data storing section b13, an authentication code input section b14, an authentication requirement transmitting section b15, a lens processing control section b16, a lens processing section b17, and a design data processing section b18.

The lens processing management device E1 includes a lens design data storing section b13, a design data processing section b18, an authentication requirement transmitting section b15, and a lens processing control section b16. In FIG. 3, only a schematic configuration according to the description of the embodiment is shown.

The communication section b10 receives data from the prescription data transmitting device a1, and the lens designing device c1 through the server b2 shown in FIG. 2. The communication section b10 transmits data to the lens designing device c1 through the server b2 shown in FIG. 2.

The prescription data transmitting and receiving section b11 receives prescription data from the prescription data transmitting device a1 through the communication section b10. The prescription data transmitting and receiving section b11 transmits the received prescription data to the lens designing device c1 through the communication section b10.

The lens designing data receiving section b12 receives lens design data from the lens designing device c1 through the communication section b10. The lens design data receiving section b12 stores the received lens design data in the lens design data storing section b13. The lens design data includes identification information for identifying the lens design data.

The lens design data includes, for example, as surface-shaped data, at least one of information about an aspheric surface, a surface formed by synthesizing an astigmatic surface and an aspheric surface, a progressive focus surface, a surface formed by synthesizing a progressive focus surface and an astigmatic surface, a surface formed by a progressive focus surface, an astigmatic surface, and an aspheric surface, and a free-form surface causing a lens operation as a glasses lens when light passes through a front face and a back face of the lens. The lens design data includes, for example, at least one of information about a blank material shape, a refractive index of a blank material, a thickness of a lens, an outer diameter of a lens, and an outer circumferential shape. The lens design data includes, for example, at least one of information about an S frequency of a lens, a C frequency, an axis degree, a prism, and eccentricity.

In the authentication code input section b14, the identification code of the authentication section 224 of the semi-finished lens product 222 is input by an operation of a user, or is detected through a predetermined detection section. The authentication code input section b14 outputs the authentication code to the authentication requirement transmitting section b15.

The authentication requirement transmitting section b15 transmits a requirement that is a confirmation requirement including the authentication code and the identification information of the lens design data and is an authentication requirement for requiring determination of the authentication code to the lens designing device c1 through the communication section b10.

That is, the authentication requirement transmitting section b15 transmits the authentication requirement for authenticating the processing of the lens to the lens design data use management device E2 to be described later before performing the processing of the lens using the lens design data. The processing of the lenses is performed one by one, and the authentication requirement transmitting section b15 transmits the authentication requirement for each lens.

The design data control section b18 receives an authentication response that is a response of the authentication requirement, and determines whether or not the authentication is permitted. When the authentication response is the authentication permission response (the use permission response), the design data control section b18 reads the lens design data from the lens design data storing section b13.

In this case, the design data control section b18 outputs the read lens design data to the lens processing section b17. The lens processing control section b16 outputs control information for starting the processing of the lens to the lens processing section b17. That is, when the use permission is received, the design data control section b18 makes the design data into a state where the design data is actually usable.

Meanwhile, when the determination result is a response (hereinafter, referred to as an authentication non-permission response) representing authentication non-permission, an error message representing that the processing of the lens cannot be performed is output to a monitor (not shown).

The lens processing section b17 processes the lens using the lens design data input from the design data control section b18, according to the control information input from the lens processing control section b16.

<Lens Designing Device>

FIG. 4 is a schematic block diagram illustrating a configuration of the lens designing device c1 according to the embodiment.

The lens designing device c1 includes a communication section c10, a prescription data receiving section c11, a prescription data output section c12, a lens designing data input section c13, a lens design data transmitting section c14, a lens designing section c30, an authentication requirement receiving section c15, an authentication processing section 226, a lens design data using information storing section c17 (a first-time permission response date and time storing section), an authentication responding section c18, and an accumulated processing number calculating section c19.

The lens design data use management device E2 includes an authentication requirement receiving section c15, an authentication processing section 226, a lens design data using information storing section c17, an authentication responding section c18, and an accumulated processing number calculating section c19. In FIG. 4, only a schematic configuration according to the description of the embodiment is shown.

The communication section c10 receives data from the lens processing device b1 through the server c2 shown in FIG. 2 and transmits the data. The prescription data receiving section c11 receives the prescription data from the lens processing device b1 through the communication section c10, and outputs the prescription data to the prescription data output section c12. The prescription data output section c12 outputs the prescription data input from the prescription data receiving section c11, to an output device such as a monitor or a printer. The prescription data from the prescription data output section c12 is transmitted to the lens designing section c30. The lens designing section c30 designs a lens using the input prescription data, and outputs the design information of the lens to the lens design data input section c13.

The design information of the lens designed for the prescription data output by the prescription data output section c12 is input to the lens design data input section c13. The lens design data input section c13 generates lens design data causing the input design data of the lens to include the identification information, and outputs the generated lens design data to the lens design data transmitting section c14. The lens design data transmitting section c14 transmits the lens design data input from the lens design data input section c13 to the lens processing device b1 through the communication section c10.

The authentication requirement receiving section c15 receives the authentication requirement from the lens processing device b1 through the communication section c10, and outputs the authentication code included in authentication requirement, the identification information of the lens design data, and the reception date of the authentication requirement, to the authentication processing section 226.

The authentication processing section 226 performs the authentication of the authentication code. The authentication processing section 226 reads the accumulated processing number corresponding to the identification information of the lens design data input from the authentication requirement receiving section c15, from a lens design data using information management table (FIG. 5) of the lens design data using information storing section c17.

The authentication processing section 226 determines whether or not to permit the process of the lens using the lens design data of the identification information included in the authentication requirement, from the read accumulated processing number and the authentication requirement receiving section c15.

The accumulated processing number stored in the lens design data using information storing section c17 is the accumulated processing number calculated by the accumulated processing number calculating section c19 to be described later. The first-time permission response date stored in the lens design data using information storing section c17 is the first response date of the authentication permission response stored by the authentication responding section c18 to be described later.

Hereinafter, determination based on the maximum processing number of the lens using the lens design data and determination based on the processing permission period of the lens will be described.

<Determination based on Maximum Processing Number of Lens>

First, the authentication processing section 226 determines whether or not the read accumulated processing number falls within the maximum processing number stored in advance in the lens design data using information storing section c17. When the accumulated processing number is greater than the maximum processing number, the authentication section 226 performs determination so as not to permit the processing of the lens using the lens design data.

Meanwhile, when it is determined that the accumulated processing number falls within the maximum processing number, the authentication section 226 performs determination of the processing permission period of the following lens.

<Determination of Processing Permission Period of Lens>

The authentication processing section 226 determines whether or not the reception date of the authentication requirement input from the authentication requirement receiving section c15 falls within a processing permission period (20 days in the embodiment) that is a predetermined period, from the first-time permission response date that is the first response date of the authentication permission response stored in the lens design data using information storing section c17.

When the reception date of the authentication requirement about the lens design data of the target does not fall within the processing permission period from the first-time permission response date, the authentication processing section 226 determines that the processing of the lens using the lens design data is not permitted. Meanwhile, when the reception date of the authentication requirement about the lens design data of the target falls within the processing permission period from the first-time permission response date, the authentication processing section 226 determines that the processing of the lens using the lens design data is permitted.

The authentication processing section 226 outputs the determined information as to whether or not to permit the processing of the lens using the lens design data and the identification information of the lens design data to the authentication responding section c18.

That is, when the accumulated processing number calculated by an accumulated processing number calculating section c19 to be described later is not over the maximum processing number stored in advance, the authentication processing section 226 permits the processing of the lens using the lens design data. When the reception date of the authentication requirement falls within the period stored in advance from the first response date of the authentication permission response stored in the lens design data using information storing section c17, the authentication processing section 226 permits the processing of the lens using the lens design data.

When the information input from the authentication processing section 226 is the information representing that the processing of the lens is permitted, the authentication responding section c18 considers the authentication response as the authentication permission response. Meanwhile, when the information input from the authentication processing section 226 is the information representing that the processing of the lens is not permitted, the authentication responding section c18 considers the authentication response as the authentication non-permission response.

The authentication responding section c18 transmits the authentication response including the identification information of the lens design data input from the authentication processing section 226 to the lens processing device b1 through the communication section c10. The authentication responding section c18 outputs the information of the transmitted authentication response to the accumulated processing number calculating section c19.

The authentication responding section c18 stores the time transmitted for the first time as the first permission response date in the lens design data using information management table of the lens design data using information storing section c17, for each piece of identification information of the lens design data included in the information of the authentication response information. That is, the authentication responding section c18 stores the first response date and time of the authentication permission response in the lens design data using information storing section c17, for each lens design data.

When the authentication response is the authentication permission response, the accumulated processing number calculating section c19 reads the accumulated processing number which is stored in the lens design data using information storing section c17 and which corresponds to the identification information included in the information of the authentication response (the authentication permission response) input from the authentication response section c18. The accumulated processing number calculating section c19 stores the accumulated processing number obtained by adding the number of lenses (one in the embodiment) for which the processing of the lens represented by the information of the authentication permission response is permitted, to the accumulated processing number, as the accumulated processing number corresponding to the identification information, in the lens design data using information management table of the lens design data using information storing section c17. That is, the accumulated processing number calculating section c19 calculates the accumulated processing number of the number of processings permitted by the authentication permission response.

<Lens Design Data Using Information Management Table>

Hereinafter, the lens design data using information management table will be described in detail.

The lens design data using information management table is managed by a database.

FIG. 5 is a schematic diagram illustrating an example of the lens design data using information management table according to the embodiment. As shown, the lens design data using information management table is 2-dimensional table type data formed of rows and columns, and has columns of items of the lens design data identification information, the accumulated processing number, the maximum processing number, and the authentication response transmission date. A main key of the lens design data using information management table is the lens design data identification information.

For example, in FIG. 5, the data in which the lens design data identification information is “abc12345” represents that lenses of the accumulated processing number “2” are processed using the lens design data in which the lens processing device b1 is “abc12345”, and represents permitting that the lenses are processed using the lens design data, up to the accumulated maximum processing number “4”. In FIG. 5, the data in which the lens design data identification information is “abc12345” represents that the date when the processing of the lens is permitted for the first time using the lens design data in which the lens processing device b1 is “abc12345” is the first-time permission response date “Jun. 20, 2008”.

In FIG. 5, the data in which the lens design data identification information is “bca23456” represents that the first-time permission response date is not within the processing permission period (20 days) from “Jun. 1, 2008”, in a case of the date when the lens designing device c1 receives the authentication requirement is “Jul. 1, 2008”. In this case, the lens designing device c1 transmits the authentication non-permission response.

In FIG. 5, the data in which the lens design data identification information is “cab24567” represents that the accumulated processing time and the maximum processing number are the same “20”. In this case, the lens designing device c1 does not permit the processing of the lens using the lens design data of “cab24567” any more, and transmits the authentication non-permission response.

<Operation of Lens Design Data Use management System>

Hereinafter, an operation of the lens design data use management system 220 will be described.

FIG. 6 is a flowchart illustrating an operation of the lens design data use management system 220 according to the embodiment.

The prescription data transmitting device a1 transmits the order data for placing an order of the lens and the prescription data to the lens processing device b1 (S501).

The lens processing device b1 receives the prescription data transmitted by the prescription data transmitting device a1 in Step S501, and transmits the received prescription data to the lens designing device c1 (S502).

The lens designing device c1 receives the prescription data transmitted by the lens processing device b1 in Step S502, and outputs the received prescription data to the monitor or the printer (S503).

When the lens design date designed based on the prescription data output in Step S503 is input, the lens designing device c1 transmits the lens design data to the lens processing device b1 (S504).

The lens processing device b1 receives and stores the lens design data transmitted by the lens designing device c1 in Step S504 (S505).

When a command of starting the processing of the lens using the lens design data stored in Step S505 is input, the lens processing device b1 transmits the authentication requirement to the lens designing device c1 (S506)

The lens designing device c1 receives the authentication requirement transmitted by the lens processing device b1 in Step S506, and performs the following determination.

The lens designing device c1 determines whether or not the accumulated processing number falls with in the maximum processing number (S507). In the determination of Step S507, when it is determined that the accumulated processing number falls within the maximum processing number (Yes), the lens designing device c1 performs the determination of Step S508. Meanwhile, in the determination of Step S507, when the accumulated processing number is greater than the maximum processing number (No), the lens designing device c1 performs the process of Step S510.

The lens designing device c1 determines whether or not the reception date of the authentication requirement falls within the processing permission period from the first-time permission response date (S508). In the determination of Step S508, when it is determined that the reception date of the authentication requirement falls within the processing permission period from the first-time permission response date (Yes), the lens designing device c1 performs the process of Step S509. Meanwhile, in the determination of Step S508, when it is determined that the reception date of the authentication requirement does not fall within the processing permission period from the first-time permission response date (No), the lens designing device c1 performs the process of Step S510.

The lens designing device c1 transmits the authentication permission response as the authentication response to the lens processing device b1 (S509). The lens designing device c1 transmits the authentication non-permission response as the authentication response to the lens processing device b1 (S510).

The lens processing device b1 determines whether or not the authentication response received from the lens designing device c1 is the authentication permission response (Step S511). In the determination of Step S511, when the authentication response is the authentication permission response (Yes), the lens designing device c1 starts the processing of the lens using the lens design data of the identification information included in the authentication response (S512). Meanwhile, in the determination of Step S511, when the authentication response is the authentication non-permission response (No), the lens designing device c1 ends the present operation.

In the present operation, the lens designing device c1 determines the content of the authentication response based on the accumulated processing number and the processing permission period (S507 and S508), but the invention is not limited thereto, and may perform the determination based on any one of the accumulated processing number and the processing permission period.

As described above, in the embodiment, in the lens processing, the authentication process is performed using the authentication section 224, and the processing of the lens wrongfully using the design data and the processing of the lens using the material or semi-finished product different from the semi-finished lens product provided from the lens designing enterprise are restricted.

In the embodiment, the lens design data use management system 220 determines whether or not to permit the processing of the lens based on the accumulated processing number using the lens design data by the lens design data use management device E2 and the information of the first-time processing date (the first-time permission response date) before the lens processing management device E1 performs the processing of the lens using the lens design data. When the lens design data use management device E2 determines that the processing of the lens is permitted, the lens processing management device E1 controls the processing of the lens to be performed. Accordingly, it is possible to appropriately manage the use state of the lens design data, and it is possible to prevent the lens from being processed wrongfully using the lens design data.

According to the embodiment, when the accumulated processing number is not over the maximum processing number in the lens design data use management device E2, the lens design data use management system 220 permits the processing of the lens using the lens design data, and thus it is possible to prevent the lens from being processed wrongfully using the lens design data over the maximum processing number determined by a contract or the like. According to the embodiment, in the lens design data use management system 220, the lens design data use management device E2 calculates the accumulated processing number, and thus it is possible to appropriately manage the accumulated processing number.

In the embodiment, in the lens design data use management system 220, when the reception date of the authentication requirement falls within the period stored in advance from the first response date and time of the authentication permission response, the lens design data use management device E2 permits the processing of the lens using the lens design data, and thus it is possible to prevent the lens from being processed wrongfully using the lens design data over the maximum processing number determined by a contract or the like.

A part of the lens processing device b1 in the embodiment described above, for example, a part of the authentication requirement transmitting section b15, the lens processing control section b16, or the lens designing device c1, for example, the authentication requirement receiving section c15, the authentication processing section 226, the authentication responding section c18, and the accumulated processing number calculating section c19 may be performed by a computer. In that case, a program for realizing the control function may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be realized by reading and executing the program by a computer system.

Next, still another modification example of the embodiment shown in FIG. 1 and FIG. 2 will be described with reference to FIG. 13. The description of the same constituent elements as those of the embodiment described above is omitted or simplified.

In the embodiment, as shown in FIG. 13, the lens processing management system (the lens manufacturing system, and the lens design data use management system) 270 is provided with a processing device b1 that processes a lens, an optical designing section 272 that generates shape data (design data, and processing data) of the lens about optical design, and a server 274.

For example, the optical designing section 272 is a predetermined computer program, and is stored in a medium, a device, or a memory. The server 274 stores information about the optical design as necessary. The optical designing section 272 requires the server 274 for permission of the optical design (or the lens processing). The optical designing section 272 receiving the permission may perform the optical design through the server 274 as necessary. The processing device b1 can process the lens using the design data from the optical designing section 272.

In the embodiment, the lens manufacturer B pays the lens designing enterprise C for at least one of at least one of the number of using times (the number of times of the optical design) of the server 274, and the quantity of the lens processing in the processing device b1. Additionally, the operation of the processing device b1 may be managed using the medium (a prepaid card) such as the description using FIG. 10.

In the embodiment, in the lens design or the lens processing, the permission to the server 274 is necessary, and thus the processing of the lens wrongfully using the design data is restricted.

The embodiments of the invention have been described above in detail, but the specific configuration is not limited to the description, and may be variously modified in design within the scope which does not deviate from the main concept of the invention.

In the actual manufacturing, it is possible to correct the lens design data. When a processing error occurs, it is possible to satisfactorily manufacture the lens by correcting the data such as a design value. Since the design data is a complex surface shape, it is generally difficult to cope with the correction in the lens manufacturer.

The amendment (the correction) of the design data may be performed on the design side. In this case, for example, the lens design data may be subjected to the amendment for correcting the processing error occurring at the time of lens processing. The amendment (the correction) of the design data may be performed by the processing device. In this case, for example, the lens processing device may have a configuration of performing the data amendment for correcting the processing error occurring at the time of lens processing. The design data reflecting the error of the semi-finished product may be supplied. In this case, for example, the lens design data may be data including the amendment for correcting an individual curvature gap of each semi-finished product.

For example, the lens designing data may be transmitted through a network after the lens design data is encrypted by an encryption key by the data supply device. The encrypted lens design data may be decoded by a decoding key in the processing device. The encrypted lens design data may be configured to perform the decoding process within a preset period, and may be configured to be automatically eliminated after the preset period is elapsed. The lens design data may be configured to count the number of using times of the decoding key.

The lens design data may be configured to include information whether to use any of a plurality of kinds of semi-materials, in addition to the surface shape for processing a semi-material (a semi-finished product). As necessary, as data for quality confirmation of the processed lens, the lens design data may be configured to include lens shape information such as a center thickness of a lens, an edge thickness, and an outer diameter, and lens frequency information used when performing inspection of lens refractive power using a lens frequency measurement device or the like.

The lens design data may be configured to include the surface shape data of a front face of two faces of the lens, may be configured to include the surface shape data of the back face, and may be configured to include the surface shape data of both front and back faces. The surface shape data may be configured by a point group (a group of spatial coordinates (x coordinates, y coordinates, and z coordinates) in each point of a processing face of a semi-material), may be data formed by performing surface-interpolation on the surface shape data configured by the point group, and may be data formed by converting the surface-interpolated data by an NC processing program.

An order of the lens is directly placed from the lens store to the lens designing enterprise, and the lens designing enterprise may be configured to supply the design data to the lens store. The lens store supplies the design data to the lens manufacturer, and the lens manufacturer may be configured to perform the processing of the lens using the design data. The completed lens is supplied from the lens manufacturer to the lens store.

The kind of the processed lens is not limited, and the embodiment may be applied to a single focus lens, a progressive refractive power lens, a middle progressive lens, a short progressive lens, and the like.

The enterprise receiving the lens shape data representing the shape of the lens by receiving a service of optical design of the lens can wrongfully manufacture a lens repeatedly using the same lens shape data without paying the enterprise performing the optical design, and the enterprise performing the optical design does not easily recognize the wrongness. For this reason, there is a program that the enterprise performing the optical design cannot collect a benefit which can be originally obtained.

In the technology of the related art, it is possible to copy the lens design data, and thus there is a defect that the lens may be wrongfully repeatedly processed, such as two or more lenses are processed, although the lens processing enterprise pays only for design of the processing of one lens. For example, the data displayed and output by the communication device is copied, and thus there is a defect that the lens processing enterprise may manufacture several lenses of the data.

In the technology of the related art, the lens processing enterprise may wrongfully repeatedly process the lenses, and there is a defect that the lens designing enterprise providing the lens design data cannot recognize the wrongness.

In the technology of the related art, there is a defect that it is difficult to appropriately manage the use state of the lens design data, and the lens wrongfully using the lens design data may be processed.

In an embodiment, the lens manufacturing device includes a lens data storing section that stores lens shape data representing a shape of a lens and lens data including the number of usable times, a usage number storing section that stores the number of times where the lens shape data is used, an access control section that reads the number of times where the lens shape data is used from the using number storing section, reads the number of usable times of the lens shape data from the lens data storing section, reads the lens shape data from the lens data storing section when the number of times where the lens shape data is used is smaller than the number of usable times of the lens shape data, and increases the number of times where the lens shape data is used stored in the using number storing section by the using number, a lens shape data memory that stores the lens shape data read by the access control section, and a lens manufacturing section that manufactures a lens based on the lens shape data stored in the lens shape data memory and eliminates the lens shape data from the lens shape data memory after the manufacturing.

In the lens manufacturing device, the following configuration may be employed such that the lens data may further include the usable period of the lens shape data, the access control section reads the usable period of the lens shape data from the lens data storing section, and the lens shape data is read from the lens data storing section when the usable period is not elapsed and when the number of times where the lens shape data is used is smaller than the number of usable times of the lens shape data.

According to the configuration, the lens design data use management system determines whether or not to permit the processing of the lens based on the information about the use state of the lens design data before the lens design data use management device performs the processing of the lens using the lens design data, the lens processing management device performs the control of performing the processing of the lens when the lens processing management device determines that the processing of the lens is permitted, it is possible to appropriately manage the use state of the lens design data, and it is possible to prevent the lens from being processed wrongfully using the lens design data.

In the lens design data use management system, the information about the use state of the lens design data is the accumulated processing number of performing the processing using the lens design data by the control of the lens processing management device for each lens design data, and the processing or non-processing determining section may permit the processing of the lens using the lens design data when the accumulated processing number is not over the maximum processing number stored in advance.

According to the configuration, in the lens design data use management system, the lens design data use management device permits the processing of the lens using the lens design data when the accumulated processing number is not over the maximum processing number, and thus it is possible to prevent the lens from being processed wrongfully using the lens design data over the maximum processing number determined by a contract or the like.

In the lens design data use management system, the lens design data use management device is provided with an accumulated processing number calculating section that calculates the accumulated processing number of the number of processing when the permission is performed by the processing permission response, and the processing or non-processing determining section may permit the processing of the lens using the lens design data when the accumulated processing number calculated by the accumulating processing number calculating section is not over the maximum processing number stored in advance.

According to the configuration, in the lens design data use management system, the lens design data use management device calculates the accumulated processing number, and thus it is possible to appropriately manage the accumulated processing number.

In the lens design data use management system, the maximum processing number may be equal to or less than 20 times.

In the lens design data use management system, the information about the use state of the lens design data is the first response date and time of the processing permission response, the processing or non-processing responding section stores the first response date and time of the processing permission response in the first-time permission response date and time storing section, and the processing or non-processing determining section may permit the processing of the lens using the lens design data when the reception date and time of the processing or non-processing confirmation requirement reception date and time fall within the period stored in advance from the first response date and time of the processing permission response stored in the first-time permission response date and time storing section.

According to the configuration, in the lens design data use management system, the lens design data use management device permits the processing of the lens using the lens design data when the reception date and time of the processing or non-processing confirmation requirement reception date and time fall within the period stored in advance from the first response date and time of the processing permission response, and thus it is possible to prevent the lens from being processed wrongfully using the lens design data over the maximum processing number determined by a contract or the like.

In the lens design data use management system, the period stored in advance is within 20 days.

In the several embodiments according to the invention, it is possible to suppress that the enterprise receiving the lens shape data wrongfully manufactures the lens with respect to the enterprise of the optical design source. More specifically, according to the invention, it is possible to make the lens processing using the lens shape data over the number of usable times not to be performed.
